1. An anti-roll tank trailer for lowering an overall center of gravity of the tank trailer, the tank trailer comprising:
an upper body positioned at a front end of the trailer, the upper body having an upper body height and an upper body center of gravity;
a transitioning body connected to the upper body, the transitioning body inclined relative to the upper body;
a lower body connected to the transitioning body, the lower body positioned at a rear end of the trailer, the lower body having a lower body height less than the upper body height and a lower body center of gravity, wherein the center of gravity of the lower body lowers the overall center of gravity of the trailer;
wherein the upper body, the transitioning body and the lower body have a uniform diameter;
a cavity extending through the upper body, the transitioning body and the lower body, the cavity comprising an upper cavity in the upper body, a transitioning cavity in the transitioning body and a lower cavity in the lower body, wherein the upper cavity, transitioning cavity and lower cavity are fluidly connected, the cavity further comprising an upper cavity volume, a transitioning cavity volume and a lower cavity volume, wherein the lower cavity volume is greater than the upper cavity volume;
a first portal for transitioning fluids in or out the cavity from a top portion;
a second portal positioned in the lower body transitioning fluids in or out of the cavity from a lower portion;
a wheel assembly connected to the lower body; and
a kingpin assembly positioned proximate to the upper body, adjacent the front end, the kingpin assembly configured to connect the tank trailer to a transport vehicle.
